Brain Activity in Adults With ADHD During Neuropsychological Tasks

Completed
Conditions
Attention Deficit Hyperactivity Disorder (ADHD)
Interventions
Device: MRI
Registration Number
NCT02578342
Lead Sponsor
Kantonsspital Aarau
Brief Summary

The aim of the study is to investigate the response on cognitive testing of healthy persons compared to adults with or without medication against ADHD.

Detailed Description

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most prevalent psychiatric disorders in children and adolescents. It is characterized by inattentive, hyperactive, impulsive behaviour and neuropsychological deficits. In 40-60% of cases emerge in childhood and persists into adulthood.

The aim of the study is to investigate the response on cognitive testing of healthy persons compared to adults with or without medication against ADHD. As a secondary endpoint a more robust diagnosing method combining advanced imaging methods with neuropsychological evaluation is tested.

Neuropsychological testing, functional MRI and spectroscopy will be performed. Statistical analysis will assess differences in the functional magnetic resonance imaging, spectroscopy and neuropsychological evaluation results between three groups: 1) group of healthy volunteers, 2) participants with ADHD with medication and 3) participants with ADHD without medication.
